Stent-graft treatment of mycotic aneurysms: a review of the current literature

J Vasc Interv Radiol. 2008 Jun;19(6 Suppl):S51-6. doi: 10.1016/j.jvir.2008.02.012.

Abstract

Mycotic aneurysms are rare but are associated with a high risk of rupture if not treated promptly. The early mortality rate associated with traditional surgery depends on patients' condition and can be as high as 43%. The use of stent-grafts is less invasive but the outcome is unproven in the setting of infected aneurysms. In an attempt to better elucidate the role of stent-grafts in this setting, a literature search was performed to examine 52 articles describing 91 patients with mycotic aneurysms who were treated with stent-grafts. The early mortality rate was 5.6%. Incidences of late aneurysm-related mortality and complications were 12.2% and 7.8%, respectively. The most consistent predictor of poor outcome was development of aortoenteric fistula. Although the 30-day mortality rate associated with the use of stent-grafts appears to be lower than that associated with surgery, late aneurysm-related events are frequent and warrant a more vigilant follow-up regimen than used with noninfected aneurysms.
